She told police she was going there to pay a debt she owed to Pollock, but Mangiardi said once she was inside the gym, Pollock put on a pair of black gloves and pulled out a knife, threatening to cut off her fingers and toes as collateral.

A camera at a nearby business caught Mangiardi running out of the gym asking workers there to call police.

Pollock admitted to police he did push Mangiardi and that he may have slapped her. A pre-trial conference is scheduled for July 9 at 9 a.m.

Pollock also testified in George Zimmerman's second-degree murder trial on Monday. He testified that Zimmerman trained in the form of mixed martial arts known as grappling but was an unaccomplished fighter.

"He was about a 1," said Pollock when asked to rank Zimmerman's athletic skill on a scale of 1 to 10.
